Advertisement So I have another small infestation of flies. This time I believe phorid flies. I knew I would encounter this problem at some point. The last time I had an issue with flies it was fungus flies and they were pretty managable. But this time it has all happened so fast. I put a roach in with a gravid murinus yesterday morning. I went to remove the partially munhed carcass just now and there was lots of flies in her tub. I have watered a fair few more specimens too and there was some more in them. I have set up sugar water traps and vinegar traps with sticky strips nearby. The problem I have is that I keep so many Ts in that room. It is a horrendously huge and lengthy task to swap out sub and scrub everything. My question to you nice people of the boards.. Is there a way to completely rid the flies without dumping sub and rehousing??
